  • Patent number: 6408448
    Abstract: A toilet system controller including a toilet bowl having at the bottom a discharge opening. A treating chamber has an intake opening connected to the discharge opening of the bowl. A macerator and discharge pump are located in the treating chamber, with the discharge pump discharging treated effluent to a waste pipe. A motor is operably connected to the macerator and discharge pump for effecting simultaneous operation of the macerator and discharge pump. A valve connects the toilet bowl to a source of water in order to admit water to the bowl to flush the bowl. A timer regulates operation of the motor and the valve during a flushing cycle. The flushing cycle is initiated by operation of the motor starting at time zero and continues for five seconds, followed by opening of the valve starting at time zero plus one and one half seconds and continuing for six and one half seconds.

  • Patent number: 5009776
    Abstract: A filter system for achieving continuous filtering by the provision of three filter chambers disposed about a common vertical axis, each containing a filter bed comprised of buoyant particles through which the fluid to be filtered is passed in an upward direction and wherein provision is made for rehabbing the beds of particulate material as they become filled with solids, preferably in succession to enable continuous operation.

  • Patent number: 4672689
    Abstract: A toilet system comprising a bowl, a valve for supplying flush water to the bowl, an attrition chamber to which the effluent in the bowl is transferred by a motor-driven discharge pump connected to the attrition chamber for inducting the effluent from the bowl into the attrition chamber and discharging the treated effluent from the attrition chamber, a power-driven hydraulic attrition impeller within the attrition chamber for effecting hydraulic attrition of the solid matter in the effluent while in the attrition chamber, and a control circuit for effecting sequential operation such that discharge and attrition are commenced substantially simultaneously, followed by introduction of flush water, termination of the discharge, termination of the flush water and, finally termination of the attrition.

  • Patent number: 4550452
    Abstract: A toilet system comprising a bowl, a treating chamber, a trap connecting the bowl to the treating chamber, said trap containing a bypass to a waste pipe, a conductor connecting the treating chamber to the waste pipe, a hydraulic attrition member in the treating chamber for particulizing effluent delivered into the treating chamber, a worm pump in the treating chamber for evacuating effluent from the bowl into the treating chamber and discharging the treated effluent into the waste pipe, a valve connected to the bowl for supplying flush water thereto and control means operable to initiate operation of the pump followed by operation of the valve and stop the pump prior to closing of the valve and wherein, in the event the pump is disabled, discharge from the bowl can be effected through the bypass by delivery of fluid into the bowl.

  • Patent number: 4427555
    Abstract: A filter system wherein there is a first chamber containing fluid at a predetermined level, a shroud positioned in the first chamber immersed in the fluid, said shroud defining a downwardly-open second chamber, a quantity of discrete, buoyant bodies supported in the shroud by flotation, said discrete, buoyant bodies defining a filter media, a conduit connected to the top of the shroud for delivering fluid to the shroud at a pressure to displace the discrete, buoyant bodies downwardly therein as the fluid is forced downwardly into the shroud and into the lower part of the first chamber below the shroud, a second chamber surrounding the first chamber, a conduit connecting the top of the shroud with the second chamber, a conductor connected to the bottom of the second chamber providing an outlet from the bottom and valves in the several conduits operable on the one hand to admit fluid into the shroud and to permit fluid to be withdrawn from the third chamber while blocking flow of fluid from the first chamber to

  • Patent number: 4420403
    Abstract: A filter module wherein the fluid to be filtered is projected into a chamber containing a floating bed of buoyant bodies confined within the chamber at the top side and wherein the point of entry of the fluid is constantly moved about the center of the bed so that successive portions of the bed are subjected to weltering while the remainder is quiescent such that the solids are separated from the bodies dispersed by weltering and gravitate to the bottom of the module and are drawn off and the filtrate is drawn off through the quiescent portion of the bed at the top.
